When it is desired to position a beam having a flange thickness greater than that which the arm 23. is adapted to be used with,

- as is indicated in Figure 1, the member is reversed,-as is shown in Fig. 5, the arm 24 being positioned in abutment with the spacers 9 and the other arm being positioned adjacent to the flange of the beam and upturned. a I

Since it ispossible to dispose the arm 23 at various angles to the surface of the spacer with which it abuts, depending upon the thickness of the flange, and since the arm 24 maybe likewise disposed at various angles tov the s acer, depending upon the thickness of the an e of the beam, it is, to be noted that a wi e variety and a wide range in flange thicknesses can be successfully engagedby themember 21by varying the arm positioned in abutment with the spacer. In commercial practice I have found that a beam and said spacer for engaging either of said arms with said spacer.

A retainer comprising a structural beam, a mold form adjacent said beam, a spacer disposed between and abutting said beam and said form, and a member adjustably secured to said spacer and adapted to be adjustably supported by said beam, said member including a central shank having an arm extending at substantially a right angle from each end thereof, said arms being of different lengths and extending in opposite directions.

In testimony whereof I have hereunto set my hand.

single retainer of my invention suffices to accommodate and to secure adequately all sizes andshapes of flanges ordinarily encountered in building construction.

I claim:

1. In combination with a structural beam and a :mold form, a retainer comprising a spacer adapted to be adjustably secured between said beam and said form and in contact therewith, and a memberadapted to be adjustably secured to said spacer and to be engaged with said beam; said member including a central shank and a pair of arms,

one on each end of said shank, said arms being of different lengths and extending in opposite directions and substantiallyat right angles to said shank.

2. In combination, a structural beam, a mold form having a bottom and a side adjacent said beam,espacing means disposed between said bottom and said beam and abutting said'side', a member secured to said spacing means, and a plurality of different arms on said member adapted selectively to be en aged with said spacing means.

3. retainer comprising a structural beam, a mold form adjacent said beam, a spacer adaptedto be disposed between and abuttingsaid beamand said form, a member secured to said spacer, and a pair of arms of different lengths on said member, said -member being adapted to ,be disposed in either of two positions with respect to'said Nun)
